COMMUNICATIONS SECURITY TITLE: COMSEC - Secure Voice Telephones LESSON LEARNED: NATO elements must learn to use the standard secure telephones. BACKGROUND: For future NATO-led operations, it must be stressed that the NATO secure telephone standard is the STU IIB. Augmenting forces must bring compatible equipment if it stays under national control. Must come to grips with the US and NATO secure telephones within the command. There are problems associated with US and NATO secure telephones: The STU III/STU IIIA has not been released to NATO, so they should be eliminated from the NATO comm system. The NATO standard is the STU IIIB, only the STU IIB is compatible with the STU IIIA. Cannot adhere to US security regulations for protecting US secure voice systems in an allied environment. RECOMMENDATION: Consider a letter to DIRNSA requesting relaxation of current US policy. http://call.army.mil/call/spc%5Fprod/5sigcd/2tact.htm
